Skylight window system with a ventilation device with improved flow path and method for operating the ventilation device

摘要

A roof window system has a roof window (1) having at least one frame (2, 3) defining a frame plane and including a pane (4), the roof window (1) further comprising a ventilation device (40) adapted for providing ventilation of a building in which the roof window is mounted, and a ventilation assembly (100) comprising a housing (150) accommodating at least one ventilation unit (110, 120) including at least one ventilator (131, 132; 133, 134) and at least one regenerator (171, 172), and a set of flow channel sections (1502, 1504, 1508; 1503, 1507). The ventilation assembly is connected to an aperture for air intake and exhaust, and to the ventilation device (40) of the roof window (1). In this way, a predefined flow path via the set of flow channel sections. Near the transition to the ventilation device of the roof window, the flow path in the housing (150) is divided by a splitter (1521; 1522) to form a pair of transition flow channel sections (1507, 1509; 1508, 1510) with a respective width dimension (d1, d2) and in connection with one respective adjacent flow channel section (1503; 1504) with a predefined width dimension (d0).
